This modification is no longer considered necessary for flight safety.\n\n**Who is affected**\n\nOwners and operators of Piper PA-46 (Malibu) series aircraft, and the maintenance organisations that service these planes.\n\n**Practical effect**\n\nThe flap drive modification requirement no longer applies. Aircraft owners no longer need to ensure this specific modification has been made to maintain airworthiness certification for these aircraft."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-46-6-amdt-1-flap-drive-mechanism-cancelled","history":"/api/acts/ad-pa-46-6-amdt-1-flap-drive-mechanism-cancelled/history","analysis":"/api/acts/ad-pa-46-6-amdt-1-flap-drive-mechanism-cancelled/analysis","conflicts":"/api/acts/ad-pa-46-6-amdt-1-flap-drive-mechanism-cancelled/conflicts","importantCases":"/api/acts/ad-pa-46-6-amdt-1-flap-drive-mechanism-cancelled/important-cases","documents":"/api/acts/ad-pa-46-6-amdt-1-flap-drive-mechanism-cancelled/documents"}}
